what evidence related to The Big Bang Theory best supports which one of the following ideas

It appears that the list of potential ideas is missing from the given context. Please provide the options you would like to choose from so that I can assist you further.

A .radiation from the big bang is distributed evenly in the universe

B.the elements formed by the big bang exist in the smaller ratios today
C. the universe is cooling to the point where it will start to contract
D. the universe is warming very rapidly

The evidence related to The Big Bang Theory that best supports option B is:

B. The elements formed by the big bang exist in smaller ratios today.

This idea is supported by the observation of the abundance of light elements, such as hydrogen and helium, in the universe. The Big Bang Theory predicts that these elements were formed during the early stages of the universe, and their presence and relative abundance validate this prediction.
